Long Breeze
Portable Oxygen Generator – 33% Oxygen, 3 L/min, Quiet 52dB, Model NT-5
In stock — processed in 1–2 business days
Simple to run, wherever you put it
The Long Breeze NT-5 delivers steady 33% oxygen enrichment — above the 21% in ordinary room air — in a unit that stands just 9.3 inches tall. One switch starts it. That is the whole interface. There is no menu to learn and nothing to set up, which is the point: a machine you can put on a side table and forget about between uses.
Built to be quiet
The NT-5 runs at 52 decibels or under — around the level of a quiet room. That matters most for a machine that lives beside a chair or a bed rather than one you carry. If carry weight is your priority instead, the 3.3 lb Lightweight 33% trades a little size for portability at the same concentration.
About the concentration
This unit delivers 33% ±3% oxygen at every flow level. That makes it a light-enrichment device for general wellness use, not a high-concentration machine. If you need higher output, look at our 93% model instead. The concentration guide covers which tier fits which situation.
Who it is for
People who want a straightforward home unit for daily light oxygen enrichment — reading, resting, watching TV, overnight if your doctor has said that suits you. It plugs into a wall outlet and stays put. Browse it alongside the rest of the range on the oxygen concentrators page, or read nine questions to answer before you buy. Looking after it takes a few minutes a week: here is how to clean an oxygen concentrator filter.

Three promises
Each one costs us money. That's the point.
